It's different for everyone, but I started feeling better literally the day after my first infusion. I started Remicade and 6MP at the same time, right after my diagnosis. I felt much better in the weeks following my first infusion (which is too early for the 6MP to do anything, so I'm assuming it's from the Remicade). I gradually got better and better, and I felt really good after about 3-4 months. It's been 9 months and my GI and I have not discussed the word remission, but I certainly consider myself in remission. But like I said, I started 2 meds at the same time, so it's hard to say. Hope you feel better soon!
